Description

Technical field

[0002] This utility model relates to the field of film roll packaging technology, and in particular to a linkage gripping mechanism for use in film roll packaging lines. [Background Technology]

[0004] In the field of film roll packaging production, with the continuous acceleration of industrial automation and the increasingly stringent market requirements for product packaging quality and production efficiency, efficient and precise roll handling and packaging equipment is becoming increasingly crucial.

[0005] Traditional film roll packaging methods mostly rely on manual operation or simple single-machine gripping equipment. Manual packaging has many drawbacks: the labor intensity of workers is high, the work efficiency is low, and it is difficult to ensure the accuracy of gripping and handling by manual operation, which can easily lead to the rolls shifting or falling during turnover, resulting in a high scrap rate. Furthermore, the speed of manual operation is limited by the worker's skill level and physical strength, making it difficult to meet the needs of large-scale, high-efficiency production. Frequent manual intervention can also slow down the overall production pace, increase unnecessary waiting time, and raise production costs.

[0006] While stand-alone gripping equipment alleviates manual labor pressure to some extent, its poor synchronization becomes a critical issue as the number of workstations on the production line increases and the complexity of the processes rises. When the roll material needs to be transferred between multiple workstations, each stand-alone device operates independently and cannot coordinate precisely, resulting in asynchronous gripping and transfer of the roll material, making it difficult to arrive at the designated workstation on time.

Detailed Implementation Methods

[0039] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0040] Please see Figures 1 to 10This embodiment provides a linkage gripping mechanism for a film roll packaging line, including at least two roll gripping and conveying devices 1 slidably connected to a frame 5. A linkage mechanism 2 is connected between any two of the roll gripping and conveying devices 1 to enable synchronous displacement of the two. Any one of the roll gripping and conveying devices 1 is connected to a first drive mechanism 3. The first drive mechanism 3 serves as a power supply component and is connected to any one of the roll gripping and conveying devices. By driving this device, the entire linkage gripping mechanism can be driven to work.

[0041] Specifically, in this embodiment, the linkage gripping mechanism includes two roll material gripping and transporting devices 1 slidably connected to the frame 5. Specifically, they can be slidably connected by a slider and a slide rail. Each roll material gripping and transporting device 1 is designed to grip and transport film rolls, for example, by clamping, adsorbing or other appropriate means to fix and move the roll material, and move it along the sliding rail on the frame 5 to realize the turnover of the roll material between different workstations.

[0042] A linkage mechanism 2 connects the two roll material gripping and handling devices 1, enabling the two roll material gripping and handling devices 1 to move synchronously, ensuring that they maintain a consistent moving speed during operation. The linkage mechanism 2 can take various forms, such as mechanical linkages, timing belts, chains, or other devices capable of transmitting power and motion.

[0043] One of the roll material gripping and handling devices 1 is connected to a first drive mechanism 3. The first drive mechanism 3 is the power-providing component; by driving the connected roll material gripping and handling device 1, it can drive the entire linkage gripping mechanism to work. The first drive mechanism 3 can be a motor, cylinder, hydraulic cylinder, or other power-providing device. It should also be noted that when the linkage gripping mechanism has two or more roll material gripping and handling devices 1, such as three, then there are two linkage mechanisms 2 between each pair, and only one first drive mechanism 3 is needed. However, in some embodiments, due to the requirement for driving force, two first drive mechanisms 3 may be provided.

[0044] It should be added that the working process of this coordinated capture mechanism is as follows:

[0045] a. Initial state: Two roll material gripping and handling devices 1 are located at station A and station B respectively, waiting to grip the film roll material.

[0046] b. Grabbing the roll material: The roll material grabbing and handling device 1 located at station A and station B will simultaneously grab the film roll material at both stations.

[0047] c. Synchronous movement: Driven by the first drive mechanism 3, the roll material gripping and conveying device 1 that grips the film roll at station B moves to station C. Through the connection of the linkage mechanism 2, another roll material gripping and conveying device 1 that grips the film roll at station A moves to station B, ensuring that the two devices maintain the same position and speed.

[0048] d. Releasing the roll: When the two roll gripping and conveying devices 1 reach the target station, the film roll is released.

[0049] e. Return to initial state: Under the action of the first drive mechanism 3 and the linkage mechanism 2, the two roll material gripping and handling devices 1 return to the initial state and are ready to carry out the next turnover operation.

[0050] Through the connection of the linkage mechanism 2, the two roll material gripping and handling devices 1 can achieve synchronous displacement under the drive of the first drive mechanism 3, ensuring that the film roll can be accurately gripped and transported to the designated workstation during the packaging process, realizing efficient turnover of the roll material between multiple workstations. The linkage gripping mechanism proposed in this embodiment makes the turnover of the roll material between multiple workstations more efficient and accurate, reduces manual intervention and waiting time, and improves the overall production efficiency of the packaging line.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the linkage mechanism 2 includes at least two connectors 21, and each connector 21 has a connecting portion on both sides to connect with any two adjacent roll material gripping and conveying devices 1.

[0052] Specifically, in this embodiment, the linkage mechanism 2 includes at least two connectors 21. Each connector 21 has connecting portions on both sides for connecting two adjacent roll material gripping and conveying devices 1. These connecting portions can be made using methods such as bolt connections, pin connections, snap-fit ​​connections, or other methods that can secure the connection. Through the connection of the connectors 21, two adjacent roll material gripping and conveying devices 1 can achieve synchronous displacement, ensuring that they maintain a consistent moving speed and position during operation.

[0053] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the roll material gripping and conveying device 1 includes a sliding frame 11 slidably connected to the frame 5, and two opposing transverse moving components 12 are slidably connected to the sliding frame 11. The two transverse moving components 12 are respectively connected to lifting gripping components 13, and the two lifting gripping components 13 cooperate to grip the roll material.

[0054] In this embodiment, the roll material gripping and conveying device 1 includes a sliding frame 11 slidably connected to the frame 5. The sliding frame 11 can achieve a sliding connection with the frame 5 through the cooperation of a slider and a slide rail, and then move on the frame 5 through the first drive mechanism 3.

[0055] Two opposing transverse moving components 12 are slidably connected to the sliding frame 11. These two transverse moving components 12 can move laterally on the sliding frame 11 to adjust the distance between them. The sliding connection of the transverse moving components 12 can also adopt the cooperation of slider and slide rail or other suitable sliding mechanisms. Each transverse moving component 12 is connected to a lifting gripping component 13. The lifting gripping component 13 can move up and down to grasp and release the roll material. The two lifting gripping components 13 work together to grasp the roll material from both sides simultaneously, improving the stability and accuracy of the grasping.

[0056] The lifting gripping assembly 13 can be a cylinder, hydraulic cylinder, motor-driven screw mechanism, or other device capable of lifting movement. The gripping end below the lifting gripping assembly 13 can use clamping, adsorption, or other suitable methods to fix and move the roll material.

[0057] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the lateral movement component 12 includes a sliding mounting plate 121 slidably connected to the sliding frame 11, the sliding mounting plate 121 is connected to the lifting gripping component 13, and the sliding mounting plate 121 is provided with a second drive mechanism 122 to enable the lifting gripping component 13 to move laterally relative to the sliding frame 11.

[0058] In this embodiment, the relative positions of the two lifting gripping components 13 can be precisely adjusted by the cooperation of the sliding mounting plate 121 and the second drive mechanism 122, so as to achieve precise gripping of film rolls of different lengths and improve the stability, accuracy and adaptability of gripping.

[0059] Furthermore, as a preferred embodiment of this solution and not a limitation, the second drive mechanism 122 includes a second reducer 1221 mounted on the sliding mounting plate 121. The upper end of the second reducer 1221 is connected to a second servo motor 1222 and the lower end is connected to a second gear 1223 passing through the sliding mounting plate 121. The sliding frame 11 is provided with a corresponding rack that cooperates with the second gear 1223 to realize the lateral movement of the lifting gripping assembly 13 relative to the sliding frame 11.

[0060] In this embodiment, the second reducer 1221 is fixedly mounted on the sliding mounting plate 121 to reduce the speed of the second servo motor 1222 and increase the torque. The second servo motor 1222 is connected to the upper end of the second reducer 1221 to provide power. The second gear 1223 is connected to the lower end of the second reducer 1221 and passes through the sliding mounting plate 121, thereby ensuring that the two lifting gripping components 13 can be precisely adjusted in relative position to achieve precise gripping of film rolls of different lengths, improving the stability, accuracy, and adaptability of the gripping process.

[0061] Furthermore, as a preferred embodiment of this solution and not a limitation, the first drive mechanism 3 includes a first reducer 31 fixedly connected to the roll material gripping and conveying device 1. The upper end of the first reducer 31 is connected to a first servo motor 32 and drive shafts 33 are respectively provided on both sides. A first gear 34 is provided on one side of the drive shaft 33 to cooperate with the rack on the frame so that the roll material gripping and conveying device 1 slides on the frame 5.

[0062] In this embodiment, one of the roll material gripping and transporting devices 1 is connected to a first drive mechanism 3. The first drive mechanism 3 includes a first reducer 31, which is fixedly connected to the roll material gripping and transporting device 1 and is used to reduce the speed of the first servo motor 32 and increase the torque. The first servo motor 32 is connected to the upper end of the first reducer 31 and provides power. Drive shafts 33 are respectively connected to both sides of the first reducer 31, and each of the two drive shafts 33 has a first gear 34 connected to one end of the frame 5 near the frame 5, which meshes with the rack on the frame 5 to realize the horizontal movement of the roll material gripping and transporting device 1 on the frame.

[0063] Furthermore, as a preferred embodiment of this solution and not a limitation, the lifting gripping assembly 13 includes a mounting base 131 fixedly connected to the lateral movement assembly 12. A gripping arm 132 is connected below the mounting base 131. A lead screw 133 is vertically provided on one side of the gripping arm 132. The upper end of the lead screw 133 passes through the mounting base 131 and is connected to a third reducer 134. The third reducer 134 is connected to a third servo motor 135. A connecting block 136 that can move vertically along the lead screw 133 is sleeved on the lead screw 133. More specifically, the connecting block 136 has a built-in ball bearing that engages with the lead screw 133. A guide shaft 137 is connected below the connecting block 136. A linear bearing 138 corresponding to the guide shaft 137 is provided on one side of the lower part of the gripping arm 132. A gripper 139 is connected through the linear bearing 138 to the guide shaft 137. A guide post 1391 that can extend into the core of the roll material is provided on one side of the gripper 139.

[0064] In this embodiment, specifically, two guide shafts 137 are connected below the connecting block 136. Each guide shaft 137 passes through its corresponding linear bearing 138 and is connected to a gripper. It is important to emphasize that the gripper 139 has a guide post 1391 on its side that can extend into the core of the roll material. When the guide posts 1391 of the two grippers 139 simultaneously rise into the core of the roll material from both sides, the roll material can be hooked together, allowing for the lifting and lowering of the film roll material between different workstations. Compared to the gripping or clamping structure used in existing roll material gripping mechanisms, the grippers 139 in this embodiment can avoid potential damage to the surface of the film roll material, improving the packaging yield.

[0065] Furthermore, as a preferred embodiment of this solution and not a limitation, the gripping arm 132 has a strip-shaped hole 1321. A first limit sensor 1361 passing through the strip-shaped hole 1321 is provided on one side of the connecting block 136. First proximity switches 1322, cooperating with the first limit sensor 1361, are respectively provided along the upper and lower edges of the strip-shaped hole 1321 to limit the lifting range of the gripper 139. Through the cooperation of the first limit sensor 1361 and the first proximity switch 1322, the lifting range of the gripper 139 is limited, preventing overload or damage and improving the safety and reliability of the equipment.

[0066] Furthermore, as a preferred embodiment of this solution and not a limitation, the gripping arm 132 is provided with matching first protective covers 1323 and second protective covers 1324 on both sides, and the second protective cover 1324 is provided with heat dissipation holes. The first protective covers 1323 and second protective covers 1324 on both sides of the gripping arm 132 provide protection for the internal structure, prevent dust, debris, etc. from entering, and provide heat dissipation holes to ensure the stability and reliability of the equipment under long-term operation.

[0067] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding frame 11 is provided with a matching third protective cover 111, the third protective cover 111 is provided with a slot through which the third servo motor 135 can pass, and the third protective cover 111 is also provided with a heat dissipation cover 112 covering the third servo motor 135.

[0068] In this embodiment, the third protective cover 111 matches the sliding frame 11 to protect the sliding frame 11 and its internal structure, preventing dust, debris, and other contaminants from entering. A slot is provided on the third protective cover 111 for the third servo motor 135 to pass through, ensuring sufficient installation space. A heat dissipation shroud 112 is also provided on the third protective cover 111 to cover the third servo motor 135, preventing dust and debris from entering while providing heat dissipation, ensuring the stability and reliability of the third servo motor 135 during long-term operation, and extending the service life of the equipment.

[0069] Furthermore, as a preferred embodiment of this solution and not a limitation, a second proximity switch 1211 is installed on one side of the sliding mounting plate 121, and a plurality of second limit sensors 113 that can cooperate with the second proximity switch 1211 are installed on the sliding frame 11 to limit the lateral movement range of the lateral movement assembly 12.

[0070] In this embodiment, the cooperation of the second proximity switch 1211 and the second limit sensor 113 limits the lateral movement range of the lateral moving assembly 12, preventing the sliding mounting plate 121 from exceeding the allowable movement range and avoiding equipment damage or operational errors. Furthermore, the multiple second limit sensors 113 enable precise positioning of the sliding mounting plate 121, ensuring that the lifting gripping assembly 13 can accurately align with the roll material, thus improving gripping accuracy and efficiency.

[0071] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding frame 11 is provided with buffer devices 114 on both sides to provide pressure and shock absorption for the sliding mounting plate 121. The buffer device 114 includes an anti-collision base fixedly connected to the sliding mounting plate 121, and an anti-collision pad is provided on the anti-collision base to provide pressure and shock absorption with the sliding mounting plate 121.

[0072] In this embodiment, buffer devices 114 are disposed on both sides of the sliding frame 11 to provide pressure and shock absorption for the sliding mounting plate 121, reducing the impact and vibration of the sliding mounting plate 121 during movement. The buffer devices 114 reduce the impact and vibration of the sliding mounting plate 121 during movement, protecting the sliding mounting plate 121 and its connected lifting and gripping assembly 13, and extending the service life of the equipment. Simultaneously, by reducing impact and vibration, the stability and reliability of the equipment can be improved, ensuring that the equipment operates within its normal operating range. Furthermore, the buffer devices 114 can also reduce the noise generated during equipment operation, improving the comfort of the working environment.

[0073] Working principle of this utility model:

[0074] This embodiment provides a linkage gripping mechanism for a film roll packaging line. This linkage gripping mechanism operates through at least two roll gripping and transporting devices slidably connected to a frame. Each roll gripping and transporting device includes a sliding frame with two opposing lateral moving components slidably connected to it. Lifting gripping components are connected to each lateral moving component for gripping and transporting the film roll. The two roll gripping and transporting devices are connected by a linkage mechanism, enabling them to move synchronously and ensuring consistent movement speed and position.

[0075] One of the roll material gripping and handling devices is connected to a first drive mechanism, which serves as the power supply component. When the first drive mechanism drives the connected roll material gripping and handling device to move, it drives the other roll material gripping and handling device to move synchronously through the linkage mechanism.

[0076] The specific working process includes: In the initial state, two roll material gripping and conveying devices are located at different workstations waiting to grip the film rolls; when gripping the rolls, the two roll material gripping and conveying devices simultaneously grip the film rolls at their respective workstations; during synchronous movement, driven by the first drive mechanism, one roll material gripping and conveying device moves to the next workstation, and through the connection of the linkage mechanism, the other roll material gripping and conveying device also moves synchronously to the corresponding workstation; when releasing the rolls, the two roll material gripping and conveying devices release the film rolls after reaching the target workstation; finally, they return to the initial state to prepare for the next turnover operation.

[0077] Furthermore, this linkage gripping mechanism limits the movement range of each component through proximity switches, limit sensors, and buffer devices located at different locations. This reduces impact and vibration, protects the equipment, and improves its stability, reliability, gripping accuracy, and efficiency. Ultimately, it enables efficient and accurate turnover of film rolls between multiple workstations, reducing manual intervention and waiting time, and improving the overall production efficiency of the packaging line.

[0078] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
